Beckson's Crank Case Pump virtually eliminates the mess associated with dipstick oil changes. The Handy- Mate 212PGA is specially adapted to pump crank case oil from engines equipped with a threaded fitting on the top of the dipstick tube. Threaded adapter fits standard male garden hose couplers. Pump attaches quickly and securely. Large pump body and long pump stroke pumps out crankcase oil quickly, easily and cleanly. The Handy-Mate is made entirely of tough marine plastic. It will not rust or corrode. Handy-Mate uses non-sparking materials for safety and is self priming for almost instant pumping action.
